Upgrade to National RV

Hello!
After lots and lots of reading on this and a few other message boards, we are considering a 2007 Trop-ical T330. (Freightliner chassis 300hp Cummins and Allison 2500 6-speed trans.) We are racers and hope to upgrade our current program. Our family has been staying at the track on race weekends in a 31' class c (Ford E-450 and V10) and towing an enclosed race trailer with a crew cab dually. This system is sufficient, but requires two drivers and two hungry fuel tanks.
According to the National RV sales brochure, GCWR is 33000 on the T330. I believe it would be rated closer to 38000 if it was equipped with an Allision 3000. Mid 2000 years Itasca Meridian 32T / Winnebago Journey 32T are on the same chassis...same engine...even have very similar floor plans. They have the 3000 trans and are rated 38000. Before we passed up a deal on a 32' Meridian, I spoke with Winnebago. They indicated a dry weight of 19500 on that model. We need to stay in the 32'-33' length due to trailer a long trailer.
Our trailer has been scaled just under 8500lbs. I plan on running the Tropical across a set of scales before we sign on the dotted line to ensure we will fall within the weight rating and will not be exceeding axle weight limits. Im positive we wont be the first to top any mountains we come across, but feel this unit will have enough to get the job done. Our race schedule will require approxmately 5k miles per year...probably add a few extra thousand miles a year for family outings (reason for choosing a diesel pusher over a toterhome) I was hoping to get some feedback from the National owners about the model (any typical trouble areas) and about possible unforeseen issues that may be created by towing. Thanks in advance!

You can look at my avatar there is a Super Late model in the box. We have towed that thing all over the southeast. We have the 400 horse with 3000 Allison. Upgraded from a class c Gulfstream duramax. The National is a great motorhome to bad that they are gone. You will not regret your picking a National product IMHO.

Hey Adam, We have a, new to us, 07 T330. Love it! We haven't had any mechanical troubles. it's very roomy. With the weight of your trailer you will go up the big hills slow but it will pull it. Good luck!

good choice

we are relativley new to our 2008 National T330 goes buy model TC33A according to the floor plan. Freightliner XCR chassis with Cummins ISB 340 engine, Allison 2500 six speed tranny. Found with only 16K miles a year ago. Added solar charging for both house and chassis batteries. Went last summer up the Calif coast to Wash then on to Yellowstone towing a nissan pick up, then back over the mountains to San Jose with no pulling problems at all. Added steering stabilizer to calm down the sway of driving a big sail down the hiway, seems a little to light weight for its size even after the wife loads all her s--t in it . You should be happy with the quality and dependability of that unit.

We've not had a chance to put many miles on our 06 Tradewinds 40E (400hp ISL 3000 Allison) but are not dissapointed in the ones we have. We pull a 24' x 8.5' x 12'h with no problems loaded with toolboxes, air compressor, bicycles, kayak, Harley and the Corvette, have not hit the scales yet but figuring around 9,000.

When we looked at the National everywhere was good to really good quality, I don't think you'll be disappointed, very nice coaches. Another positive is that near all the components are generic and replacements or repairs are not a problem unlike some other manufacturers who used proprietary parts. Good Luck

Thanks for all the replies. We are going for our final (hopefully) look this Saturday. I'll be sure to send an update. We try real hard to keep and maintain things in tip top shape. Partly for ego and partly for fiscal responsibility. Our class-c is a 2003 model, but is in extremely nice condition. (always garaged ect.) This is a huge amount of money for our budget but we have the mindset that this one will be with us for at least the next 15yrs. or so. Obviously, issues can be had at anytime with anything that was built on a production level but I am satisfied that National RVs in general are as good...or better than most brands out there...at least on our end of the price range. Thanks again!

We tow a 20' box with a Sports2000 in it. The trailer has a very heavy tongue weight and I had the hitch on the TropiCal boxed to the Freightliner frame. Tows well. After fading the RV brakes in stop and go traffic through Seattle, I keep the trailer brakes (all 4 wheels) and controller adjusted for max braking out of the trailer.

The only additional improvement I would make would be a trailer tug, so I could just get the trailer close with the RV and then walk it into position in the paddock.

We now officially belong to the National RV owners family. I am going to pick it up next Saturday (3/28)

First up on the list of improvements is a new set of "shoes" to replace the original '07 tires. Im hoping they (tires) will get me home (350mi) The coach/tires only have 31000 miles and show no sign of sidewall cracks, but we all know that doesnt mean a thing.
Freightliner/National specd a 255/70/22.5 tire on 7.5 wide steel wheel for this coach. I would like to put the new tires on a set of aluminum wheels. (cause Im a hot rodder)
A 7.5 wide aluminum wheel is sorta rare/expensive. Has anyone replaced the 7.5 wide wheels and 255/70/22.5 tires with the much more common 8.25 wheels...and maybe a 275/70? I know we will have to verify stud length for the thicker aluminum wheel, but would like to know if this has been done...and is a good idea/bad idea.

Looking forward to lots of experiences and adventure with our new-used TropiCal and becoming knowledgeable enough to assist other National owners! -Adam

Our '04 TropiCal T350 has 22.5 x 8.25 aluminum wheels w/ 255/80 tires. Get the right offset & I think you should be just fine.

Welcome to the family - our TropiCal has been terrific.
